The Company has the following material Exclusive Channel Collaboration (“ECC”) agreements:

The Lantibiotic ECC

On June 5, 2012, the Company entered into the Lantibiotic ECC with Intrexon that governs a “channel collaboration” arrangement in which the Company will use Intrexon’s advanced transgene and cell engineering platforms for the development and production of lantibiotics, a class of peptide antibiotics that are naturally produced in Gram-positive bacteria and contain the characteristic polycyclic thioether amino acids lanthionine and methyllanthonine (collectively, the “Lantibiotics Program”). The Lantibiotic ECC grants the Company an exclusive worldwide license to use patents and other intellectual property of Intrexon in connection with the research, development, use, importing, exporting, manufacture, sale, and offer for sale of drug products involving the direct administration to humans or companion animals of a lantibiotic for the prevention or treatment of infectious disease (“Oragenics Products”). Such license is exclusive with respect to any clinical development, selling, offering for sale or other commercialization of Oragenics Products, and otherwise is non-exclusive. Subject to limited exceptions, the Company may not sublicense the rights described without Intrexon’s written consent. The Lantibiotic ECC establishes committees comprised of Company and Intrexon representatives that will govern activities related to the Lantibiotics Program in the areas of project establishment, chemistry, manufacturing and controls matters, clinical and regulatory matters, commercialization efforts and intellectual property matters. The Company has agreed to indemnify and hold Intrexon harmless from any damages caused as a result of (i) our negligence or willful misconduct, (ii) the use, handling, storage, or transport of Intrexon Materials (as defined in the Lantibiotic ECC), (iii) our breach of a material representation, warranty or covenant in the Lantibiotic ECC, or (iv) the design, development, manufacture, regulatory approval, handling, storage, transport, distribution, sale or other disposition of any Oragenics Product.

Intrexon may terminate the Lantibiotic ECC if we fail to use diligent efforts to develop and commercialize Oragenics Products or if we elect not to pursue the development of a Lantibiotics Program identified by Intrexon that is a “Superior Therapy” as defined in the Lantibiotic ECC. We may voluntarily terminate the Lantibiotic ECC at any time upon 90 days written notice to Intrexon. Upon termination of the Lantibiotic ECC, the Company may continue to develop and commercialize any Oragenics Product that has been, at the time of termination:

•

commercialized by the Company;

•

approved by regulatory authorities;

•

a subject of an application for regulatory approval that is pending before the applicable regulatory authority; or

•

the subject of at least an ongoing Phase 1, Phase 2 or Phase 3 clinical trial in the Field (in the case of a termination by Intrexon due to an uncured material breach by the Company or a voluntary termination by the Company).

The Company has ongoing obligations and commitments with respect to the Lantibiotic ECC. See Note 12 — Commitments and Contingencies.

The Oral Mucositis ECC

On June 9, 2015, the Company entered into an the Oral Mucositis ECC with Intrexon and Intrexon Actobiotics NV (“Actobiotics”), a wholly-owned subsidiary of Intrexon, through which the Company intends to research, develop and commercialize products, including the continued development and commercialization of AG013, for use in the treatment of oral mucositis in humans through the administration of an effector via genetically modified bacteria, but, in any case, excluding the delivery of anti-cancer effectors for the purpose of treatment or prophylaxis of cancer (collectively, the “Program”). Contemporaneously with the Oral Mucositis ECC, the Company and Intrexon also entered into a Stock Issuance Agreement (the “SIA”) which authorized the issuance of the Technology Access Fee and the future stock issuance of our Common Stock to Intrexon upon the achievement of designated milestones. The ECC governs the “channel collaboration” arrangement in which we will use Intrexon’s proprietary technology relating to the identification, design and production of genetically modified bacteria (the “Technology”) for the purpose of developing the Program. The Oral Mucositis ECC provides for the establishment of committees comprised from us and Intrexon representatives that will govern activities in the areas of project establishment, chemistry, manufacturing and controls, clinical and regulatory matters, commercialization efforts, and intellectual property. The Company has agreed to indemnify and hold Intrexon harmless from any damages caused as a result of (i) our negligence or willful misconduct, (ii) the use, handling, storage, or transport of Intrexon Materials (as defined in the Oral Mucositis ECC) or materials that are Actobiotics IP (as defined in the Oral Mucositis ECC), (iii) our breach of a material representation, warranty or covenant in the Oral Mucositis ECC, or (iv) the design, development, manufacture, regulatory approval, handling, storage, transport, distribution, sale or other disposition of any Oragenics Product.

The Oral Mucositis ECC grants the Company an exclusive worldwide license to utilize Intrexon’s and Actobiotics’ intellectual property to develop and commercialize products, including the continued development and commercialization of AG013, for use in the treatment of oral mucositis in humans through the administration of an effector via genetically modified bacteria, but, in any case, excluding the delivery of anti-cancer effectors for the purpose of treatment or prophylaxis of cancer (the “Field”). It also grants us an exclusive license in the Field under all Information Controlled by Actobiotics (or otherwise by Intrexon) and existing as of the Effective Date relating to the regulatory approval of AG013, including regulatory filings, data, clinical trial reports, and rights thereunder. Under the Oral Mucositis ECC, and subject to certain exceptions, we are responsible for, among other things, funding the further anticipated development of products toward the goal of commercialization, conducting preclinical and clinical development of candidate products, as well as for other aspects of manufacturing and the commercialization of the product(s).

The Company may voluntarily terminate the Oral Mucositis ECC upon 90 days written notice to Intrexon. Intrexon may also terminate the Oral Mucositis ECC if the Company breaches and fails to cure the breach within 60 days or the Company does not pursue development of the Superior Therapy identified by Intrexon that is a “Superior Therapy” as defined in the Oral Mucositis ECC. Upon termination of the Oral Mucositis ECC, the Company may continue to develop and commercialize any Company Product that, at the time of termination that satisfies at least one of the following criteria:

(i)

the particular Oragenics Product is being sold by the Company triggering profit sharing payments under the Oral Mucositis ECC to Intrexon;

(ii)

the particular Oragenics Product has received regulatory approval;

(iii)

the particular Oragenics Product is a subject of an application for regulatory approval in the Field covered by the Oral Mucositis ECC that is pending before the applicable regulatory authority;

(iv)

the particular Oragenics Product is AG013, and such Oragenics Product has been the subject of at least one completed Phase 2 clinical trial (as such is defined by relevant FDA guidelines) during the Term; or

(v)

the particular Oragenics Product other than AG013 and such Oragenics Product is the subject of at least an ongoing Phase 1, Phase 2 or Phase 3 clinical trial in the Field.

Among other things, Intrexon is responsible for technology discovery efforts, cell-engineering development, and certain aspects of the manufacturing process. See Note 12 — Commitments and Contingencies.

The entire disclosure for collaborative arrangements in which the entity is a participant, including a) information about the nature and purpose of such arrangements; b) its rights and obligations thereunder; c) the accounting policy for collaborative arrangements; and d) the income statement classification and amounts attributable to transactions arising from the collaborative arrangement between participants.
